Radiofrequency interference complaints 2012-13

To give stakeholders and other citizens better insights into our investigations work, we present this statistical breakdown of the interference investigations work we have recently done and are currently doing. Where investigations are ongoing, or have not been published, the ACMA is generally unable to give detail of the entities and issues involved for individual matters or otherwise make comment. The following tables are prepared from information collected for each interference investigation activity according to standardised terminology and events.

Note: One ACMA compliance activity may involve a complaint to the ACMA on behalf of a number of affected households in a neighbourhood or involve several types of broadcasting services.
